Abstract
An object-lens driving device for an optical pickup and which employs such a fine pattern coil as is used in a compact disk player or a laser disk player. The object-lens driving device for an optical pickup eliminates the rolling phenomenon caused when a wire having a circular cross-section is used as a supporting member. Focusing and tracking are controlled more stably, since a plurality of plate springs is used for elastically biasing the horizontal or vertical movement of a driving portion body.
